Hi Perl Monk,

I have a .h file with the different macro definition like given below snippet 

{
  #define thread 1
  #define flag
  #define code 0
  #define const (100/5)
  #define flag_condn 1
}

I need to extract only variable which is assigned with 1 or 0 or blank space, like my out put has to be 
{
 thread 
 flag
 code 
 flag_condn 
}

Here is my perl which I am not able to get properly in case of #define flag which has a blank space, I used split function, 
while (<INPUT>) {
 my @split_data = split(' ', $_);
 if($split_data[2] == " "||$split_data[2]==1||$split_data[2] == 0){
 print "$split_data[1]\n"
 }
}
